Can the two go together?

What I noticed is before I processed an issue about someone where I set some new boundaries (learning ....), I must have been so low. I think that because lately I intentionally try to do enjoyable things like reading fiction or watching videos. And it's been nice when not tiring me out too fast. But when this issue started, I noticed that I just couldn't stop reading the book and start doing what I had to do instead. (E.g. work or sleep) It felt like addiction????

How do you manage this, you are supposed to do some nice things for yourself to help feel better but if it gets addictive like this as a distraction and then you feel like you can't control it, what can help?
